>Description:
I can't get any program to run that tries to use GPU acceleration on
my RPI 1b rev2 (earmv6hf).
Tried this with both a self-built image and Jun's latest image (so 8.99.12),

Even hello_triangle.bin under /usr/pkg/src (not /usr/pkgsrc), part of
raspberrypi-userland, returns this error when run:

 * failed to add service - already in use?

With Linux this error message has historically been caused by firmware
issues, or a suboptimal gpu_mem split. I've tried gpu_mem=32, 64, 128
and even 256, to no avail.
I've also swapped the firmware for older versions that I've been using
on my RPI2 with NetBSD (same version).
>How-To-Repeat:
1. download raspberrypi image 

http://cdn.netbsd.org/pub/NetBSD/misc/jun/raspberry-pi/2018-02-11-earmv6hf/2018-02-11-netbsd-raspi-earmv6hf.img.gz
http://mail-index.netbsd.org/port-arm/2018/02/06/msg004579.html

or the build server images (earmv6hf or earmv7hf)

2. copy to microsd

gunzip < 2018-02-11-netbsd-raspi-earmv6hf.img.gz |dd of=/dev/rsd0d bs=4m

3. setup Raspberry PI 0/1/2/3
- microsd card
- connect HDMI
- USB keyboard

4. extract pkgsrc 2017_Q4

5. build misc/raspberrypi-userland

6. build hello_triangle from /usr/pkg/src/hello_pi/ or any other example program that uses 3D acceleration. Note that this needs some paths adjusted and LD_LIBRARY_PATH specified when running.
This also applies to any package that uses 3D acceleration.

 This is perhaps the same problem as port-evbarm/52984:

 Module Name:	src
 Committed By:	rin
 Date:		Wed Aug 22 13:16:41 UTC 2018

 Modified Files:
 	src/sys/external/gpl2/dts/dist/arch/arm/boot/dts: bcm283x.dtsi

 Log Message:
 Explicitly disable v3d, pixelvalve, and hvs for bcm283x at the moment.

 When these devices or hdmi are enabled, firmware turns off GPU functionality of
 VideoCore, expecting OS drivers handle it appropriately:

 https://github.com/raspberrypi/firmware/issues/763

 This breaks userland applications using /dev/vchiq, such as omxplayer.

 XXX We need enable them back when we import vc4 drm driver.

 Fix PR port-evbarm/52984 and
 PR port-arm/53042.

 OK jmcneill, skrll

State-Changed-Why:
Now, hello_triangle works fine with new *.dtb files on my Raspberry Pi 3.

Could you please confirm fix?

Note that besides *.dtb, you need kernel newer than 2018-08-19 with this fix:
http://cvsweb.netbsd.org/bsdweb.cgi/src/sys/arch/evbarm/conf/files.evbarm#rev1.31

Otherwise, you cannot open /dev/vchiq.
